To all whom it may concern:

Be it known that 1, ANDREW THOMA, a citizen of the United States, and resident of Cambridge, in the county of Middlesex, and State of Massachusetts, have invented an improvement in Shoe-Bottom Fillers, of which the following description is a specification. i

The object of my present invention is to provide a shoe filler material which is unlike the material at present in use, in that it possesses a great amount of resiliency (i. e. cushion-like eflect in a, shoe), equaling, if not surpassing, the resiliency of the pure and best grades of rubber in sheet form.

My intention is to use, in place of the usual granulated form of cork, leather dust,

ground leather, or similar dissected material for a filler-body, a mass of coagulated oil, which, when prepared for my particular purpose, resembles a mass of crawling maggots when disturbed.

The coagulated ground oil can be prepared in various ways so that its shredded particles may be firm and dry, or its process.

of treatment may be one to allow a certain softness to the mass which also gives the In other full of life, easily aixed to suitable bind ing agents, and readily, spread within the shoe cavit i Various methods may be pursued to solidify bodies of various vegetable oils. it may be done by a simple prolonged boiling process, or it may be brought about by sulfurizing or treatments with acids. The methods of oxidizing of oils are so'numerous that it is not necessary for me to enumerate them. It is primarily the product which enters in a ground, shredded, or otherwise dlssected state into-my novel filler material that is of importance here. i To render this crawl-'- ing ground oil matter fit to be readily workable so as to form a resilient, compact layer within a shoe bottom; to make it quickly conformable, adhesive and cohesive without destroyingits resiliency is the second teature of my invention. For this purpose it use a binding material such as is described in my patent No. 945,294, dated January 4, 1910, (which is subordinateto my foundation or pioneer filler Patent, No. 832,002 pf Sept. 25, 1906)viz. a permanently elastic,

quicksetting, sticky mass contag a gelat- Specification of Letters Patent.

inous base. For instance, 1 may use one and a half ounces of pure caseln, one quarter ounce of borax, six ounces of water, one half ounce of glycerin (all dissolved in a water bath into a smooth flowing solution), five ounces of rosin (naphthalene-dissolved), two ounces wax tailings (petroleum), and one third ounce of Wilmington tar; or, eight ounces of bone glue, three ounces of glycerin, eight ounces of water, two ounces of calcium chlorid, heated to 160 degrees F., and dissolved into a smooth flowing, permanently smooth fluid solution, to which I add four ounces of rosin (dissolved in naphthalene), and one quarter ounce of creosote oil. The foregoing two preparations may be applied to the filler body-in a heated condition and thus installed within a shoe bottom, or they may be rendered by an addition of water i tions, 1 may use two ounces of corn starch (or any other starch) swelled and dissolved with soda lye z. e. arabol' or apparatin, etc., one ounce of glycerin, (this being an example of one of the well-lmown water-soluis the olein oil of my application, Serial No. 591,207,) eight ounces of rosin (dissolved in v naphthalene), three ounces of petroleum tailings, one half ounce of Wilmington tar, or any combinations oflike materials which will provide a tenacious, elastic binding medium.

Certain of the foregoing binders are covered also in my copending applications Ser. No. 432,083, filed May 11, 1908,,now Patent No. 1,032,312, dated July 9, 1912, and Serial No. 591,207, filed November 7, 1910, now Patent No. 1,134,931, dated April 6, 1915.

The'mixing' of the filler-body material with the bindercan be done by hand or with ordinary rotating machinery for this purpose,and when thoroughly admixed to a pasty condition, it can be spread easily with a tool in the shoe bottom.

The set material (when in a shoe-bottom cavity) composed of a highly resilient bodygiving component and a like adhesive agent admixed as stated above to stick the mass ble fat-derived oily liquids, another of which 7 to the leather innersole and to hold the 'sheeted layer of filler material-in a strong tenacious manner, .is the result of my present invention and constitutes the said second feature of the invention.

A third novel feature of my new filler. lies in its application within the shoe botv tom by providing the operator with a special solution for immersing the working tool, or a revolving roll which is traveling in a solution of a precipitant, so that when the filler material is spread within the shoe cavity, the revolving roll is not only leveling the material but is also uniting with it at the same time a chemical precipitant which makes the binding fluid substantially insoluble by water and adds greatly to its protection during the wear of the shoe. This makes a homogeneous filler mass or layer and is in no sense a multiple-layer shoe-sole structure, which latter is therefore mentioned).

Another way to overcome this moisture influence of the binding agent is the use, within the cementitious preparation of a percentage of sticky resinous matter which, upon the drying and setting of the material, is preponderatingly large, to protect the gelatinous base from dissolution by water under ordinary conditions (as covered, for

example, in my copending application Serial v the filler-components of my new shoe-bottom filler may consist of a gluey or gelatinous No. 432,983, filed May 11, 1908).

That the principles as set forth in my present invention may be brought about by a large and varied use of materials is very evident, and, although I do not prefer it, instead of using the ground coagulated oil,

base treated with glycerin and oils in such a manner as to become a permanently highly resilient ass, such, for example, as compo- 'sitions used for printers rolls, which, when ground and mixed with a cementitious fluid,

will produce a material similar to a sulfureted oil as previously described.

My invention includes any natural or artis ficial spongy, resilient mass which can beground to proper size so as to become conformable as a special component of the filler mass, and it also includes any combination which would require or permit the changing of the solvents, as, for instance, whenever water-absorbing components are used to provide the filler body, a changing to a naphtha solution of the so-called rubbers which I mean to' include rubber, gutta percha, or like materials (which would not injuriously affect the said filler body components) to bind and cement and render waterproof the otherwise to moisture yielding or absorbing mass I consider would come clearly within the meaning of my present invention. I also wish to embrace various means, such as fiuify, light weight materials to act as an additional body-giver to the resilient body forming mass. Ground or shredded leather is the best known material of this kind in the shoe-making trade. This may be added while the coagulation of the rubbery matter is about to take place, by making the same very porous (like a sponge), or it may be added to the mixed ingredients as a cheapening agent.

My Patent No. 945,294, of January 4, 1910, provides for a filler made resilient with a comminuted filler body and a gelatinous highly resilient binding component; such material therefore would depend mainly for its resiliency upon the binding means, but my present filler aims to increase the resiliency still further by providing a filler body which is highly resilient or cushion-like as well as the binder, so that the use of the above described method and means for a filler material provides a long sought for cushion for the foot which is at the present time gained through felt with the so-called cushion innersoles.

My new filler material will enable the shoev ber of commerce, thereby gaining an unchangeable cushion as it does not oxidize, which is impossible with a felt innersole.

A layer of this new resilient filler may also be applied to the heel portion of a shoe, thereby forming and providing additional ease to the foot of the wearer which is now sought for by the use of rubber heels.

Having described my invention, what I claim asnew and desire to secure by Letters Patent is: s

1. A shoe filler, comprising a resilient body of coagulated oil in a dissected condition held together in a permanently and highly resilient, cushion-like, adhesive and cohesive condition. with a permanently resilient, sticky, cementitious binder which permits the filler to constitute a cushion in a shoe-bottom.
